The entire system of circuits illustrated 'iriFig. 1- is divided into two'groups, one group 'insolid lines, within a suitable cabinet not shown, and the other, shown in dotted lines, suitably located in the bank or store to be protected; The circuits are shown in their simplest form in Figs. 2 to 3. In Fig, 2,.the battery A is shown as supplying current to a closed high resistance or super-vised? circuit,:f1owing from the plus pole-of the battery r 5 55, 50-"ohmmagnet 19, wire 20, 1800 ohm magnet 21, 2000 ohm resistance 22, wire 23,8.5 hmmagnet-24,wire 25, to negative of battery. Owing to :thehigh resistance Qfthema'g'net'ZI, and the 2000 ohm resistance 22,- the current flowing is very weak, but is sufiicient to energize the magnet21,

and'keep the contact :26 open. Suitable push but- :tons,.fo'ot contacts,' etc.,-27 are located atdesired placesfin' the banker store. Upon closing one of :the foot contacts 27', the 1800011111 magnet 21 and 2000.0hm resistance 22 are short circuited, and the current therrflowsas indicated bythe heavy lines inFig; 3, through magnets 19 and 24 -111156- ries, providing a currentstrong enough to snap gize magnet l9which attracts the armature 2 8, 100

closingcontact 29fandlconnecting the8.5 ohm magnet 24 through wires 16, 30, 3land 25 direct .to the battery. A bell-ringing current alsofiows from the positive pole of the battery through 7 wires 16, 30,119, bell 111, contact 26, wire25, to 1 the, negative side oi the battery. The increased current flowing through wire 30, contact 29, armae ture 23, and wire 31 energizes magnet 24: thereby actuating'the armature 32 (Fig. 1) of the intermittent ieed 'glevice 100, which then turns the 10,

ratchet wheel 38 one notch and moving the arm 34 which is secured to the ratchet wheel 33, and closing a circuit through contact plate 35 and contact 36, the current then flows from the plus end of the battery through wires 16, 30, contact 37, wire 38, warning lamps 39, which are distributed in the bank, ten ohm resistance 40, wire 41, contacts 36, 34, 35, wire 25 to the negative of the battery. Upon releasing thejfoot contact 27, the magnet 21 is again energized, opening the contact 26, deenergizing magnet 19 and leaving the circuit as illustrated in heavy lines in Fig. 4,

, with the signal or warning lamps 39 burning. The warning lamps 39, shown in Fig. 15, are located on the desks of the bankclerks, also in the several ofiices, etc., andserve to give notice that afoot contact 27, or a push button, has been operated. If the foot contact or push button was.

operated by accident, the circuit may be restored to. the original condition (Fig, 2) by an operator "opening the cabinet door (not shown), which automatically opens the tamper switch 17 actuated by the door, and the operator then closing the reset switch 43 (Fig. 7) which closes the circuit through wires 16, 110, 8 ohm reset magnet 45, reset switch 43, wires 46 and 25; the reset magnet 45 attracts armature 47, Fig. 1 andpermits the spring 48 to restore the ratchet wheel 33 to its original position, breaking-the circuit 34, 35, 36,-

(Figs. 3 and 4,) and reestablishing the circuit shown in Fig. 2.

If an attack by bandits, etc., is'being made upon the bank or store, a clerk or other official of the bank, etc., operates any one of the foot contacts or push buttons 27, twice or more in succession; the first contact closes the circuits de scribed above, and illustrated in Figs. 2, 3, and 4; the final operation of the foot contact or push button 27, establishes the oircuitshown in Fig.

5, in which themagnet 241s again energized,

,drawing the armature 32, which turns the ratchet wheel 33, thereby shifting the contact arm 34 from contact 36, as in Figs; 3' and 4, to contact 50, Figs. 5and 6; a new low resistance circuitis established through wires 16, switch 17, wire 18, gas guns 55,'wires 51, 52, contact 50 wires 56 and '25 to the battery; a circuit is also established through the alarm bell 54 from wires 16, '30, 110,

53 bell54 to wire 52, contact 50, wires 56 and 25.

'Iheincreased current flowing in the circuits established by the second operation of the foot contact ,27, and illustrated in- Figs. 5 and 6, discharge the gas guns and'continuously ring the alarm 7 bell 54, which may be located outside of the building, Upon release of thefoot contact after the second or subsequent operation, the circuit shown in Fig.6 is permanently-established until'the gas guns 55 have exploded, upon which the current in wire 18is interrupted if the resistance 70 is deastroyed, but the circuit through the bell 54 remains intact, continuously sounding an alarm until anoperator opens the cabinet and closes thereset switch 43, (Fig. 7) which actuates the reset 8 ohmjmagnet 45, thereby restoring the contact'arm34 to the original position (Figl 2) as above described, the contact arm 34 breaking the circuit through the contact 50 and restoring the {circuit connection illustrated in Fig. 2. New gas cartridges are then inserted in the gas guns 55. .The above description and ratchet feed 100 show that the guns 55 are exploded on the second or subsequent contact of the. foot contact 27; how- 'ever the intermittentfeed device 100 may be made to require three successive contacts, or any desired number of successive contacts, to discharge the guns 55. l

The gas guns 55 shown in Figs. 9, 10, and 11, consist of tubular receivers 64, in each of which is placed a cartridge containing an irritating and disabling gas composition, for example a tear gas composition 66; the cartridges mounted on a socket 67 and provided with contact terminals 68. Within the socket is an electric fuse 69, and a resistance wire 70 in shunt with the fuse 69; within the socket 67 isa firing powder 71. The guns 55; are suitably mounted at desirable locations, and may be placed in a molding 72 along the counters, shown in Fig. 11, or at other suitable places and finished to be in keeping with the surroundings, so as not to be readily noticed by outside parties. When fired, the cartridges are exploded and the irritating gas liberated and and resistance wire 70 are in shunt, the wire 70 providing a permanent path for the current should the fuse 69 be defective; the wire 70 may be destroyed the firing of the gas guns 55, but is preferably so constructed and located as not to be destroyed by the firing of the gun, thereby providing a continuous and uninterrupted circuit in the event that one cartridge should be exploded before the others; the continuous circuit through the wire 70 thereby prevents an open circuit by the discharge of one gun, and maintains the current until all of the guns have been discharged.

The foot'c'ontacts 27, or push buttons, or other circuit closures, are suitably located at the desks or counters or at other desirable places. One form of a foot contact 27 is illustrated in Figs. 12, 13, and 14, and preferably consists of a metal structure '75, supported on ends 76, and containing'an upwardly or outwardly movable bar 77 controlled by the spring 105 in the switch 80, and moved by the upper movement of the foot, as shown in Fig. 13. The bar 77 is suitably swiveled, and is-provided with a pressure arm 78 which rests on'the spring. controlled plunger 79 of a suitable contact switch 30, Fig. 14, within which are mounted contact blades81, contacts 82 and spring 105. When the foot is raised, Fig. 13, the bar 77 is moved outwardly, as shown in dotted lines, thereby pressing the arm 78 against the plunger 79, which closes the contacts 81, 82, shown in Fig. 14. When in a normal position the contacts 27 are open as shown in the circuit in Fig. 2; upon making abontact once, the circuit in Fig; 3 is established; upon making a second 'eontactwith the foot contact 27, the circuits of Figs. 5 and 6 are established and .the gas guns exploded as described above. If a break should accidentally occur in any of the vital parts of the circuit, the current through the 1800 ohm magnet 21 and 2000 ohm resistance 22 would be interrupted, thereby closing the contact 26'and ring the alarm bell 111 thereby calling attention tothe fact that the protection system was out of iis iso

16, 30, 62, ammeter 63, contact 61, and wire 25. Upon releasing the button switch60, contact 61 is broken and contact 37 is reestablished, and the circuit restored as shown in Fig. 2.
